background: due to their specific nature, such as high incidence, high intensity and direct involvement of all members of society, traffic injuries are of particular importance. through a mega data, this study investigated the epidemiological aspects and depict current situation of road traffic injuries in iran. methods: using legal medicine and traffic police data, deaths from road traffic inj...

OBJECTIVES Associations between cardiovascular mortality and air pollution and noise together were investigated. METHODS Data from the ongoing Netherlands Cohort Study on Diet and Cancer (120,852 subjects; follow-up 1987-1996) were used. Cox proportional hazard analyses were conducted for the association between cardiovascular mortality and exposure to black smoke, traffic intensity on the ne...

In the theory of traffic flows the main characteristics are: intensity, speed, and density.  They make it possible to use hydrodynamic models. In connection with the development of modern highways and road networks, traffic flows behavior is becoming more and more complex and diverse. In particular, the B.Kerner studies have shown that the laminar solution of hydrodynamic models is poorly corre...

This paper investigates the effects of congested freeway traffic conditions on motorists’ exposure to trafficrelated air pollution using real-world traffic data and a framework of established emissions and dispersion models. The intent is to isolate and compare the influences of congested traffic characteristics on exposure duration and exposure intensity. Mass inhalation of carbon monoxide (CO...

Channel allocation algorithms for channelized cellular systems are discussed from a new perspective, viz., fairness of allocation. The concepts of relative and absolute fairness are introduced and discussed. It will be shown that under certain reasonable assumptions, there exists an absolute (max-min) fair carried traffic intensity vector (a vector describing the traffic carried in the cells of...
